Hovatter Road Airstrip

The All-Arizona Star Party is at the Hovatter Airstrip: Travel time about 2 hours.

From Phoenix:

  • Go west on I-10 to Hovatter Rd at exit 53 or about 40 miles west of Palo Verde Nuclear Power Generating Station.

  • Turn left over the freeway, drive over the canal.

  • When you cross the canal, turn hard left.

  • Go 1.1 miles to a bend in the road.

  • As the road veers to the SE, look for a road running due south at the same point--- VINEGAROON ROAD. Take it for 1.8 miles.

  • You will come to a small left-right zig-zag, then see a chain link fence enclosing an area about 20 ft by 20 ft. That’s the airfield entrance.

Hovatter Road Airstrip Site is the location of the this year's All-Arizona Star Party. The observing field is located about 90 miles west of Phoenix, along Interstate 10, just south of the Hovatter Rd exit (Exit 53). The sky conditions are very good, similar to  those of the old Vekol Road site and the former AASP site, Farnsworth Ranch.

This new site is classified as '2' on the Bortle scale, defined as having faint shadows cast by the Milky Way visible on white objects. Clouds are black holes in the sky. No light domes. The Milky Way has faint extensions making it 50 degrees thick. Limiting magnitude 7.1 to 7.5.  Sky brightness is 21.99 to 21.89 mags per square arc second.

The site offers the right combination of dark skies, good visibility and temperate nights that will encourage you to stay up well past your bedtime! It is important to note that this site is on US BLM land, and the hosts of the AASP have a permit from the US BLM for its usage. This is a primitive site - so if you need something you'll have to bring it with you! Porta-Potties will be available on site. Attendees are welcome to camp overnight at AASP.
